I would think that concern trolls, despite having "troll" in their name, could be considered unintentional trolls. They're often seem quite sincere in their meddlesome desires, but it sure as hell seems like they just do it for the lulz sometimes. If one were to suggest that to them, they would be horrified, but since they're usually just doing it to feel better about themselves, that seems to put them pretty squarely into the troll camp.
